I thought I'd try this tool to see what happens. I am very impressed! In Photoshop-speak, this is called the Magic lasso which allows you to surround just the area of an image you want to keep and removes the rest, leaving a blank background you can change later.
The leaves are what I kept and saved as a copy. Unfortunately, the ZFlip Gallery app, as far as I'm aware at this stage of my exploration, doesn't allow for changing backgrounds. So, I created this image using the Lumii app. What do you think?
